cvalh said: "You know, i was in on this convo too... And I feel like I'm being shot down when I wasn't incorrect. If you take the same volume of muscle and fat, the muscle WILL weigh more. If you take more fat, the fat might weigh the same or more than the muscle. And, of COURSE 10 lbs is 10 lbs, no one is arguing THAT."

spectrachic311 said: "Yes, this is an interesting topic of debate...the wording is what's confusing, I think. Muscle and fat are different substances entirely. From a metabolic standpoint, they require different amounts of energy. Muscle is a lot denser than fat. You can see that pretty easily just by going to the grocery store and looking at some cuts of meat in the butcher department. Look at the weight printed on a good, lean cut of beef. Then look at the weight on some ground beef that is only say 75% lean. The ground beef will look bigger in comparison even if the weight is the same. Muscle has high density. I just recently went in for a physical exam and floored the nurse with my body stats; apparently she's never seen a woman with a RHR of 39 beats/min and body fat % of 12%. I wear a size 3 or so in clothes, but I weigh about 116 (depending on the day, lol). I have a friend who is my height (5'4") and who weighs the same as I do. She is 26% fat though and wears a 7 or 8. So I am more "dense" than she is. Which is fine. I'd rather be sculpted and smaller and weigh a bit more. Who can tell what you weigh just by looking at you anyway?"

See my response to you there please."
stroutman81 said: "Also Razor, after reading this post that you did here, I hope there was not a misunderstanding some place. This post almost mimmicks mine, only mine had some attitude and a lot more verbage, haha. You can tell he is associated with the ACSM as I am with the NSCA. Both are premier certification boards with high standards.
As I too stated, you must include density in any conversation that arises about fat and muscle. This was something that you chose to leave out and I was only adding it to the convo. I am sorry if I came across as rude in my reply to your post in "any ideas" but I just felt like you were attacking my post.
After looking back at my original post in "any ideas," I do see it as being primitive and not very informative.....however, I just wanted to get density and volume into the discussion because of its importance. But I really did view it as just that, a "discussion" and not an argument. Your words clearly were argumentative and defensive.
I hope you did not feel like I was attacking you, or your post. I do however, stand by anything that I replied to you in "any ideas." Truthfully, I am still pretty fired up....haha. But also, I am not looking to make enemies here either. That is completely not my intentions. If you ever feel offended by me or the need to lash out in my direction, please do so privately using the private message section of this page. I am sure we can handle it privately instead of publically as you seem to be an educated person that is capable of making rational decisions. I assure you, that I too am rational and well versed and educated when it comes to fitness and health. There is no sense to compete.
I like to help as many people as I can, but need to realize that short and quick posts will not do any good. I need to thoroughly explain what I say, just as any educated person should."

"One pound equals one pound regardless of whether the pound is fat, muscle or some other substance like butter or steel. Muscle is denser and therefore takes up a smaller amount of space per pound than fat. Some scientists estimate that the "space" that one pound of muscle occupies is about 22% less than one pound of fat! If a woman begins strength training and eats exactly the same number of calories that she did before she began lifting weights, she may lose some weight because she is burning additional calories while exercising. Even more important is the change in her body composition. She will have gained muscle and lost fat...even if she her body weight stayed the same. In our experience, most women drop a dress size or two after they have been strength training for a couple of months because their body shape has changed for the better. ""

"Another common weight lifting myth is one of the most popular in the world of exercise: "Muscle weighs more than fat."
How ridiculous is that? It's like the old joke, "Which weighs more, 10 pounds of iron or 10 pounds of feathers?"
Hopefully, by now you realize that the answer to that question is that they actually weigh the same. 10 pounds is 10 pounds no matter what it consists of.
Let's discuss this in a little more detail. Muscle tissue is a lot more compact and dense than fat. Because of this fact, it actually takes up less space than fat. Makes sense, right?
Fat tissue, on the other hand, is very soft and jelly-like so it's a lot larger than muscle. By that I simply mean it takes up more space than muscle.
Let me give you another example to clarify this concept even more: If you were to take 10 pounds of fat and 10 pounds of muscle and roll each of them into a ball, the ball of fat might be the size of a bowling ball. In comparison, the ball of muscle would be about the size of a baseball.
Let's take this one step further and use you and your friend in an example: Let's say you and your friend are both 5' 5" tall and weigh the exact same at 130 pounds.
Your friend, as mentioned earlier, doesn't lift weights or do any kind of strength training. Her dress size is a size 12.
You, on the other hand, follow a strength-training program and lift weights 3 times a week. You wear a size 8 dress.
If you and your friend were standing side by side, people would surely believe that your friend weighed more than you. But in reality you both weigh exactly the same!
How can that be? It all goes back to what I said earlier. Muscle doesn't weigh more than fat. They weigh exactly the same! Muscle is more compact than fat, so you, who lifts weights, have more muscle than your friend does which means you take up less space.
That's why it's a bad idea to let the scale be the judge of your weight lifting and fitness progress. You can easily have lost weight, but it often won't show up on the scale. A better indication of progress is how well your clothes fit. If you're getting smaller, or should we say more compact, you'll notice that your clothes are getting looser.""
